Clunk from the Rear

So I put on my new wheels today (17 to 18) and I went for a test drive. I noticed where was a clunk whenever I'm driving. Sounds like the rear bearings are bad? I did the wobble test on my wheels (Holding top and bottom of wheel then jiggling) but nothing. It happens whenever I spin the wheel and it makes a noise every rotation from what I can tell. I know it can't be from just up one size on wheels.

I know my wheels aren't hitting anything because I took the wheels off and rotated the rotor and it still happens. My brake pad sensor is on and my rear pads are worn pretty badly. Positive that can't be one of the things that is causing it though. Anybody have any idea? I am on coilovers cranked all the way down on H&R. Hopefully someone can chime in. I will be going to the dealer tomorrow to check it out.

pop the car in the air on the wheel u think the noise is coming from and do a spin test and look really good. there are hub bearings on all four corners behind your rotors

Do you have extended lug bolts or is the wheels the same offset? I had to get some extended lug bolts for my car and they were a bit too long, therefore it rub the parking brake spring behind the brake disc.

Offset is 50 on 10" wide wheel. I don't think I have extended as they're only 27mm long which is oem isn't it? But yea I brought it to the dealer and it does happen to hit the parking brake. For now I have the wheels off getting then redone. Will get some bolts after I figure it out.

in my situation, the hub on my Hre wheels is a bit thinner causing the bolt to go in further into the brakes. What I did was cut off a few millimeter of the bolt and no more rubbing.

Was going to do that but I was afraid they might get weaker. How did you cut them?

I used a Dremel with the reinforced cutoff wheel, clamping the bolts to a vise grip or similar clamp. Yea the set I cut wasn't my oem, I bought an extra set but ended up being too long. Cutting it might not be a good idea if it's going to be too short if you had to change wheel.

+1 - The bolts should be through hardened so OK to cut.
